Summary: Zwitterionic peptides with loop-like structures exhibit better antifouling properties by resisting protein and bacteria adsorption, being more rigid compared to linear-like peptides, reducing interaction with foulants, improving hydrophilicity, and avoiding chain aggregation. This study provides a comprehensive understanding of the conformation effect of zwitterionic peptides, which may contribute to the design of novel antifouling materials in various biomedical applications.

Summary: This research examined how linear or branched brushes on porous ultrafiltration membranes affect their antifouling behavior. By modifying polyethersulfone membranes, different polymer brushes were created using a one-pot lithiation/acylation process. Surface analyses showed differences in brush architecture and higher grafting for linear brushes compared to branched ones. Colloidal probe lateral force atomic force microscopy (LFM) demonstrated that lower branching degree poly(SBMA-co-MBAm) had ideal hydration-lubrication properties. Fouling experiments with bovine serum albumin and dextran showed that both linear and branched modifications reduced fouling compared to the pristine membrane. The study also found that an optimal degree of branching can limit foulant adsorption.

Summary: Zwitterionic peptides with histidine and glutamic acid, as well as lysine and glutamic acid, sequences were synthesized and tested for protein and marine organism resistance. A comparison revealed that peptides with lysine performed better against proteins and freshwater bacteria, while sequences containing histidine were more resistant to marine organisms. The influence of amino acid properties and external factors on coating resistance was discussed, providing insights for future biocompatible and sustainable fouling release coatings.

Summary: Designing zwitterionic polymers and enhancing antifouling properties of membrane surfaces are important for water reclamation. In this study, a facile and scalable one-pot polymerization approach was proposed to synthesize a novel thiolated zwitterionic polyurethane (TZP) and graft it onto a polydopamine activated membrane surface for antifouling nanofiltration (NF) membranes. The TZP grafting neutralized the negative charge of the membrane surface, improved its hydrophilicity, and optimized the pore size and ion selectivity of the NF membranes. The TZP-30 membrane exhibited excellent fouling resistance and satisfactory flux recovery rate.

Summary: This study demonstrates two different routes to synthesize polymer-dendrimer hybrids with advantageous self-assembly properties onto silicon oxide surfaces. The first route yields network-like structures with crosslinked PLL and ZIDs, while a more defined linear PLL-ZID macromolecule is formed through a controlled CuAAC click reaction. The potential use of these hybrids as antifouling coatings and for selective detection of target analytes is confirmed through various testing methods.

Summary: The study found that changes in the elastic properties of brain tissue are associated with injury, cancers, and neurodegenerative diseases. Different methods were used to measure the apparent Young's modulus of brain tissue, with volume-controlled cavity expansion providing more accurate measurements of the nonlinear mechanical properties of intact, healthy mammalian brain tissue. Accurate estimation of elastic properties in strain-stiffening tissues like the brain requires appropriate constitutive models, such as the Ogden model included in VCCE.

Summary: This study presents a new strategy to achieve antibacterial and anti-biofouling behavior on commercial UF membranes without compromising their size selectivity and pure water permeance. By codepositing a strong antibacterial agent (CTAB) with dopamine onto the membrane surface in the presence of nitrogen gas backflow, the pore size and pure water permeance of the membrane remained unchanged. The results demonstrate that the membrane functionalized with CTAB at the critical micelle concentration exhibited the best anti-biofouling activity and retained its surface zeta potential even after being stored in a saline solution for 3 months.

Summary: This study investigated the impact of changing the pH value of PEDOT:PSS/PVA solution on the morphology and electrical properties of electrospun nanofibers. It was found that neutral and slightly basic PEDOT:PSS/PVA solutions could be electrospun without affecting the electrical properties. However, the electrical properties of the fibers decreased when exposed to solutions with pH values between 5 and 11, as well as with agitated soap washing tests.
